我正在尝试从另一个列表生成列表:
lista = [u'http://www.fetise.com/apparel/shirts',
u'http://www.fetise.com/apparel/tees',
u'http://www.fetise.com/apparel/tops-and-tees',
u'http://www.fetise.com/accessories/belts',
u'http://www.fetise.com/accessories/cufflinks',
u'http://www.fetise.com/accessories/jewellery',
u'http://www.fetise.com/accessories/lighters',
u'http://www.fetise.com/accessories/others',
u'http://www.fetise.com/accessories/sunglasses',
u'http://www.fetise.com/accessories/ties-cufflinks',
u'http://www.fetise.com/accessories/wallets',
u'http://www.fetise.com/accessories/watches',
u'http://www.fetise.com/footwear/boots',
u'http://www.fetise.com/footwear/casual',
u'http://www.fetise.com/footwear/flats',
u'http://www.fetise.com/footwear/heels',
u'http://www.fetise.com/footwear/loafers',

u'apparel/tees/gifts-for-her',
u'footwear/sandals/gifts-for-her',
u'footwear/shoes/gifts-for-her',
u'footwear/heels/gifts-for-her',
u'footwear/flats/gifts-for-her',
u'footwear/ballerinas/gifts-for-her',
u'footwear/loafers/gifts-for-her']
通过使用这个:
^{pr2}$输出为:
[u'http://www.fetise.com/apparel/tees/gifts-for-her',
u'http://www.fetise.com/footwear/sandals/gifts-for-her',
u'http://www.fetise.com/footwear/shoes/gifts-for-her',

u'http://www.fetise.com/footwear/ballerinas/gifts-for-her',
u'http://www.fetise.com/footwear/loafers/gifts-for-her']
但我需要这个输出:
